Nikon announces FX-format AF-S NIKKOR 70-200mm lens

Fixed f/4 aperture throughout the entire focal range

As its name suggests, Nikon's newest optic has a 70-200mm focal length with a fixed f/4 aperture throughout the entire range to boost low-light performance. As an added bonus, the fixed aperture means that photographers won't need to adjust exposure settings while tracking a subject with the telephoto, unlike variable-aperture lenses.

The NIKKOR 70-200mm boasts 20 optical elements in 14 groups, constructed of extra-low dispersion (ED) glass to reduce chromatic aberrations. Nikon's Super Integrated Coating is included as standard, along with a Nano Crystal Coating to reduce reflections and eliminate ghosting and flaring. The autofocus system is provided by a Silent Wave Motor (SWM) system, switchable between autofocus with manual override (M/A Mode) and manual-only (M Mode) through a switch on the side of the lens.

The NIKKOR 70-200mm is the first lens to feature Nikon's third-generation Vibration Reduction technology, again selectable using a dedicated switch on the lens body, which offers a claimed shake reduction functionality equivalent to up to five focal stops - something that should make the lens more usable hand-held at higher telephoto levels.

The lens is due to launch in late November, with UK pricing yet to be set. Nikon has, however, released US recommended retail pricing, with the lens itself due to cost $1399.95 and supporting an optional tripod collar priced at an additional $223.95 (around £870 and £139 excluding taxes.)
